    摘要: There is disclosed a method for the manufacture of a crosslinked superabsorbent polymer material. There is further disclosed a crosslinked superabsorbent polymer material manufactured with the method. Using the new polymer material the previously used undesired chemistry based on polymerization of acrylamide is avoided and the less desired chemistry based on polymerization of on acrylic acid is significantly reduced. In addition the present polymer material is renewable. In contrast to the state of the art lignin does not have to be removed from the hydrolysate, so that energy, time and cost are saved and inexpensive raw materials and inexpensive process streams can be used. Lignin in the polymer material gives stronger bindings resulting in improved mechanical properties of the material. The presence of lignin further makes it possible to modify the hydrophilicity of the crosslinked polymer material. The raw materials are typically not valuable foodstuffs.

    摘要: The present invention relates to a method for utilizing a wood hydrolysate obtained from a hydrothermal treatment of a wood material method comprises the steps of providing a wood material, treating the wood material by means of an aqueous hydrothermal treatment so that a wood hydrolysate and a wood residue is formed. The wood hydrolysate comprises oligo- and polysaccharides as the main component of dry matter. The method further comprises the steps of; separating the wood hydrolysate into at least a first and a second fraction and using at least one of the at least first and second fractions for production of an intermediate or end product. Such end product may be e.g. a film, coating, package or a gel. The present invention also relates to a polymer product such as a film, a coating or a gel and its applications. The present invention provides for biodegradable and renewable polymer products and a method which utilizes and extracts a very high product value from a process.
